Need advice asap!!!

[Worried mom]

Hello, my name is crystal and I'm 20 years old. I started a light pink bleeding on April 28th. It lasted from April 28 to may 2nd. I started my actual period on may 2nd and ended my period on may 5th. I am curious if it could have been implantation bleeding???*
But this morning at about 3:25 I had some dull/sharp pains by my right ovary, and lighter pains by my left, and finally a light pushing sensation tword the top of my stomach. I can eat, but sometimes I feel like i will throw up but I don't. I drink alot of liquids ( mostly water or Gatorade or koolaid) I have noticed I feel bloated, my lower back , right over back right hip hurts. My husband says I have huge mood swings, and I'm always grumpy. And my appitite is dissipating. I noticed that I'm sleeping way more than I normally do. I sleep at least 13 to 16 hours a day waking up eriodicly for bathroom breaks, food, water, ect. Another thing I have noticed is that I still have lactation from my first birth which was back in 2011 ( I was 17, had been raped, and gave my daughter up for adoption) and it's gotten a little heavier, I'm not sure what this could mean .. It's nerve racking.... I could really use some help or advice please..,*
